I was able to resolve the sync issue with my Blaze. I have an iPhone and decided to look at the Fitbit iOS forum. There was an answer there that worked for me. The Fitbit app on my iPhone needed to be updated. The reply I found included a link to be directed to the App Store and once the update completed I did the soft reset— left and lower right buttons—- my Blaze synced and at least for the moment, seem back to normal.🤞😊
Hope this helps.
